Glass Wool Insulation Price in Pakistan – Technical Guide, Density, Thickness & Thermal Performance
Professional glass wool insulation solutions for steel roofs, warehouses, factories, PEB buildings, dairy sheds, poultry sheds, HVAC systems, ceilings and commercial buildings across Pakistan.
Glass wool insulation is a lightweight fibrous insulation material used to reduce heat transfer and sound transmission through roofs, walls, ceilings and HVAC systems. Its actual thermal performance depends on thickness, density, thermal conductivity, installation quality, compression and facing. For Pakistani steel sheds and roofs, 50mm (2-inch) glass wool is a commonly specified starting point, while thicker insulation can be selected where a higher thermal resistance is required.
Glass Wool Insulation in Pakistan
Glass wool insulation in Pakistan is widely used where controlling heat gain, heat loss and reverberation is important. It is manufactured from glass-based mineral fibres that form a network of tiny air spaces. Those air spaces reduce heat transfer and also provide useful acoustic absorption.
For industrial and commercial construction, glass wool is particularly useful below PPGI, PPGL, GI and other metal roofing systems. It can also be incorporated into wall systems, false ceilings, HVAC ductwork and partition assemblies.
Silver Steel Mills supplies insulation solutions for steel buildings and industrial applications, with the specification selected according to roof construction, climate, required thermal performance, thickness, density and project budget.
Glass Wool Price in Pakistan – What Actually Determines the Rate?
A single “glass wool price” is not technically reliable because the rate changes with the specification. Before comparing quotations, confirm all of the following:
- Thickness – 25mm, 50mm, 75mm, 100mm or project-specific thickness
- Density – kg/m³
- Thermal conductivity – λ value in W/m·K
- Roll, blanket, board or pipe insulation form
- Foil-faced, kraft-faced, tissue-faced or unfaced construction
- Brand and manufacturing quality
- Required quantity and project location
- Transportation and installation requirements
For an accurate glass wool insulation price in Pakistan, Silver Steel Mills can quote according to the actual roof area and required specification rather than giving a misleading one-size-fits-all rate.
Glass Wool Density: 10, 12, 16, 18, 22 & 26 kg/m³
Density is expressed in kg/m³. It tells you how much glass-wool material is contained in one cubic metre. However, density alone should not be used as a guarantee of thermal performance. The correct comparison is the manufacturer's declared thermal conductivity (λ) at a stated test temperature.
| Density | Typical Planning Position | Indicative λ Range* | 50mm Approx. R-Value* | Typical Applications |
|---|---|---|---|---|
| 10 kg/m³ | Lightweight insulation | ~0.045–0.050 W/m·K | ~1.00–1.11 m²·K/W | Light roof/ceiling applications where suitable |
| 12 kg/m³ | Light commercial blanket | ~0.042–0.046 W/m·K | ~1.09–1.19 | Roofs, ceilings and general thermal insulation |
| 16 kg/m³ | Medium-density option | ~0.038–0.042 W/m·K | ~1.19–1.32 | Steel buildings, roofs and commercial projects |
| 18 kg/m³ | Medium-density roof insulation | ~0.037–0.040 W/m·K | ~1.25–1.35 | PEB, warehouses and industrial roofs |
| 22 kg/m³ | Higher-density blanket/board range | ~0.035–0.039 W/m·K | ~1.28–1.43 | Commercial and higher-performance applications |
| 26 kg/m³ | Higher-density insulation | ~0.034–0.038 W/m·K | ~1.32–1.47 | Higher-performance roofs, walls and technical applications |
*Technical note: The λ and calculated R-value figures above are indicative engineering-planning ranges, not a product certification. Actual values vary by fibre structure, binder, facing, thickness, test method and manufacturer. For procurement or specification, use the manufacturer's current technical datasheet. R-value is calculated approximately as thickness ÷ thermal conductivity.
Which Glass Wool Density Is Better for a Roof?
There is no universal “best density.” The correct selection depends on the building and the required thermal and acoustic performance.
10–12 kg/m³
Suitable where a lightweight insulation blanket is required and the project is primarily focused on economical thermal control.
16–18 kg/m³
A practical range for many commercial roofs, steel buildings, warehouses and PEB applications when combined with appropriate thickness.
22–26 kg/m³
Higher-density material can be selected where the project specification calls for greater material robustness or a particular thermal/acoustic performance.
Glass Wool Thermal Resistance – How Much Heat Can It Handle?
This question is often misunderstood. Thermal resistance and maximum service temperature are two different specifications.
1. Thermal Resistance
Thermal resistance describes how strongly the insulation resists heat flow. For a given material, increasing thickness generally increases R-value. For example, if a 50mm layer has a thermal conductivity of 0.040 W/m·K, its theoretical thermal resistance is approximately 1.25 m²·K/W.
2. Service Temperature
Service temperature is the temperature at which the insulation product can be used without unacceptable deterioration. It depends on the glass fibre product, binder, facing and intended application. Building glass wool products can have different service-temperature limits, while specialised technical glass wool products may be engineered for substantially higher temperatures.
For a roof, the more important design questions are the required U-value/R-value, thickness, thermal conductivity, solar exposure, ventilation, roof-sheet colour, air leakage and installation method. For boilers, furnaces or hot equipment, use a dedicated high-temperature insulation specification rather than ordinary building glass wool.
Glass Wool Thickness Guide – 25mm, 50mm, 75mm & 100mm
| Thickness | In Inches | Typical Use | Performance Consideration |
|---|---|---|---|
| 25mm | 1 inch | Ceilings, partitions and lighter insulation requirements | Lower thermal resistance than thicker systems |
| 50mm | 2 inch | Steel roofs, warehouses, PEB and commercial buildings | Common balance of thickness, cost and performance |
| 75mm | 3 inch | Higher-performance roof and wall systems | Higher R-value when properly installed |
| 100mm | 4 inch | High-performance thermal envelopes and selected industrial applications | Higher insulation level but increased material and detailing requirements |
Glass Wool Roll Size & Coverage
Glass wool is supplied in different roll and slab dimensions depending on manufacturer and product. A common building-roll configuration is approximately 1.0–1.2m wide with project-specific roll lengths. Always calculate coverage from the actual manufacturer's stated dimensions instead of assuming every roll has the same area.
For example, a roll measuring 1.0m × 15m has a theoretical area of 15m², which is approximately 161.5 sq ft before considering cutting waste and overlaps.
Required rolls = Total insulation area ÷ Net coverage per roll
Add an appropriate allowance for cutting, overlaps, roof geometry, penetrations and installation waste.
Foil-Faced Glass Wool vs Unfaced Glass Wool
| Feature | Unfaced Glass Wool | Foil-Faced Glass Wool |
|---|---|---|
| Thermal insulation | Yes | Yes |
| Radiant heat control | Limited | Foil can contribute to radiant-heat control when installed correctly |
| Vapour control | Depends on assembly | Can provide a vapour-control layer when properly detailed |
| Roof application | Suitable in appropriate assemblies | Often preferred for metal-roof systems |
| Cost | Generally lower | Generally higher |
Where Is Glass Wool Insulation Used in Pakistan?
Roof and wall insulation for improved thermal comfort and controlled indoor conditions.
Used below metal roof and wall cladding as part of the building envelope.
Helps reduce solar heat transfer through metal roofing when correctly designed.
Supports environmental temperature management alongside ventilation systems.
Used in selected duct insulation systems to reduce heat gain/loss and sound transmission.
Roof, ceiling, partition and acoustic applications.
Helps control roof heat and improve acoustic comfort.
Roof and ceiling insulation where the construction system allows proper installation.
Glass Wool for Steel Roofs & PEB Buildings
Metal roofing can become a significant source of solar heat gain because steel conducts heat rapidly and the external surface is directly exposed to sunlight. Glass wool installed as part of a properly designed roof assembly reduces conductive heat transfer between the outer roof and the interior.
However, insulation is only one part of the thermal system. A better-performing steel building may combine:
- Light-coloured or reflective roof coating/sheet where appropriate
- Correct glass wool thickness and density
- Foil facing where specified
- Properly supported insulation without excessive compression
- Sealed laps and penetrations
- Ventilation where required
- Correct roof and wall detailing
- Appropriately sized cooling and air-conditioning equipment
Glass Wool vs Rock Wool vs EPS Sandwich Panel
| Material | Main Strength | Typical Consideration | Common Applications |
|---|---|---|---|
| Glass Wool | Lightweight thermal + acoustic insulation | Needs correct support and detailing | Roofs, walls, HVAC, ceilings, PEB |
| Rock Wool | High-temperature and fire-performance applications | Usually heavier and denser | Industrial, fire-rated and technical systems |
| EPS Sandwich Panel | Integrated insulated panel system | Fire performance depends strongly on core and system specification | Walls, cold rooms and selected roofs |
Glass Wool Installation for a Steel Roof
- Inspect the roof structure: Confirm purlin spacing, sheet arrangement and support conditions.
- Select the specification: Confirm thickness, density, λ-value and facing before procurement.
- Prepare the insulation: Keep rolls dry and protected from damage before installation.
- Install without unnecessary compression: Excessive compression can change the designed thickness and thermal performance.
- Control joints and gaps: Gaps around edges, penetrations and joints can reduce the effectiveness of the insulation layer.
- Secure the material: Use an appropriate mechanical support system according to the roof design.
- Install facing correctly: Foil-faced products should be installed according to the manufacturer's orientation and vapour-control requirements.
- Complete the roof assembly: Coordinate insulation with roof sheets, flashing, gutters, ventilation and penetrations.
Glass Wool Handling & Safety
Glass wool fibres can irritate skin, eyes and the respiratory system during cutting and handling. Installers should use suitable gloves, protective clothing, eye protection and respiratory protection appropriate to the product and work environment. Keep the material dry and follow the manufacturer's safety data sheet and installation instructions.
Does Glass Wool Make a Shed Completely Cool?
No insulation material can guarantee a fixed indoor temperature by itself. Glass wool reduces heat transfer; it does not replace ventilation, reflective roofing, air-conditioning, exhaust fans or proper building design.
The actual indoor temperature depends on external temperature, solar radiation, roof colour, roof orientation, insulation thickness, thermal conductivity, wall construction, ventilation, air leakage, occupancy and cooling capacity.
Therefore, claims such as “glass wool always reduces indoor temperature by exactly 10°C or 15°C” should not be used as a universal engineering guarantee. A project-specific thermal calculation or site measurement is more reliable.
How to Choose Glass Wool for Your Project
- Tell us the building type: warehouse, factory, dairy shed, poultry shed, office, marriage hall, PEB or residential building.
- Provide the roof area: total roof square feet or length × width.
- Select thickness: commonly 50mm for many roof applications, with thicker options where required.
- Select density: 10, 12, 16, 18, 22, 26 kg/m³ or another specified value.
- Confirm facing: unfaced, aluminium foil or another approved facing.
- Confirm performance: request thermal conductivity and relevant fire/service-temperature data.
- Calculate quantity: include cutting and installation allowance.
- Request the complete delivered quotation: material, facing, accessories, transportation and installation should be clearly separated.
Glass Wool Insulation Price in Lahore, Karachi, Islamabad & Across Pakistan
The glass wool price in Lahore, Karachi, Islamabad, Rawalpindi and other cities can differ because of brand, density, thickness, facing, quantity, freight and availability. Comparing two products only by “price per square foot” can therefore produce the wrong conclusion.
For example, a 25mm low-density product and a 50mm higher-density foil-faced product are not equivalent products even if both are quoted per square foot.
For large projects, ask the supplier to quote the complete specification: thickness + density + λ-value + facing + roll size + coverage + quantity + delivery.
Why Buy Glass Wool Insulation from Silver Steel Mills?
Insulation can be selected according to the actual building application.
Useful for PEB, warehouse, shed and industrial roof applications.
Coordinate insulation requirements with the roof construction system.
Solutions can be planned for projects in Lahore, Islamabad, Rawalpindi, Karachi and other regions.
Frequently Asked Questions About Glass Wool
What is glass wool insulation?
Glass wool is a fibrous mineral insulation material made from glass-based fibres. Its structure traps air and reduces heat transfer while also providing acoustic absorption.
What is the glass wool price in Pakistan?
The price depends on thickness, density, facing, brand, roll size, quantity and delivery location. A meaningful quotation should specify all of these factors rather than only giving a generic per-square-foot rate.
Is 50mm glass wool good for a roof?
50mm (2 inch) is a common starting specification for many steel-roof applications. Whether it is sufficient depends on the required thermal performance, building use and overall roof assembly.
What is the best glass wool density?
There is no single best density for every project. 10–12 kg/m³ may be selected for lightweight applications, while 16–18 kg/m³ and higher densities may be specified for different commercial, acoustic or technical requirements.
Is glass wool heat resistant?
Glass wool has good thermal insulation and fire-performance characteristics, but its maximum service temperature varies by product. Always check the manufacturer's technical datasheet, especially for high-temperature industrial applications.
Is glass wool suitable for a steel shed?
Yes. Glass wool is commonly used as part of insulated steel-roof and PEB assemblies. The roof structure, purlins, insulation support, sheet profile and moisture/vapour-control detailing should all be considered together.
Does foil-faced glass wool perform better?
Foil facing can provide radiant-heat and vapour-control benefits when correctly installed, but the core insulation performance still depends on thickness and thermal conductivity. Foil is not a substitute for adequate insulation thickness.
Is glass wool the same as rock wool?
No. Both are mineral-fibre insulation materials, but glass wool is manufactured primarily from glass fibres while rock wool is made from mineral/rock-based fibres. Their density, thermal performance, acoustic properties and temperature capabilities can differ.

Glasswool Insulation in Pakistan: The Professional Guide to Thermal Control
In Pakistan’s diverse climate—where scorching summers can turn industrial sheds into ovens and chilly winters demand effective heat retention—insulation is no longer a luxury; it is a fundamental requirement. Among the various materials available, Glasswool Insulation has emerged as the industry standard for dairy farms, warehouses, marriage halls, and large-scale storage facilities.
At Silver Steel Mills (SSM), we prioritize the use of high-performance glasswool to ensure the structures we build remain energy-efficient, safe, and comfortable. This article explores why glasswool is the preferred choice for Pakistani infrastructure and how it functions as a thermal shield.
What is Glasswool Insulation?
Glasswool is an insulating material made from recycled glass fibers bonded together with a heat-resistant resin. It is spun into a wool-like texture that creates millions of tiny air pockets. These air pockets are the “secret” to its performance; they trap air and prevent the transfer of heat, making glasswool a poor conductor of thermal energy.
In Pakistan, it is most commonly applied in 2-inch thickness for roofing applications, providing an optimal balance between cost and thermal resistance.
Why Use Glasswool in Industrial & Commercial Sheds?
1. Temperature Regulation (The “Chimney Effect”)
In a metal-roofed dairy shed or warehouse, the sun’s radiant heat passes through the steel sheets, rapidly raising the interior temperature. A 2-inch layer of glasswool acts as a thermal break. It prevents the heat from radiating into the interior, keeping the shed significantly cooler. Conversely, during winter, it traps the warmth generated inside, reducing the need for artificial heating.
2. Acoustic Performance
Large sheds like Marriage Halls or Storage Warehouses often suffer from echo and noise pollution (especially during rain). Glasswool is naturally porous, meaning it absorbs sound waves instead of reflecting them. This makes it an ideal solution for event spaces where acoustics are critical for a professional experience.
3. Fire Safety & Non-Combustibility
Glasswool is classified as a non-combustible material. In high-risk environments like industrial factories or electrical rooms, it serves as a critical safety barrier that resists flame spread, providing valuable time during emergency situations.
Applications Across Different Sectors
Dairy Sheds: Essential for heat-sensitive livestock. Maintaining a consistent, lower temperature directly correlates to improved milk production and animal health.
Marriage/Banquet Halls: Beyond thermal comfort, it provides the acoustic dampening required for high-quality audio and event experiences.
Warehouses & Storage Halls: Protects inventory from heat-induced damage (e.g., food, electronics, or chemical storage) while saving massive costs on ventilation and cooling systems.
Technical Specifications & Pricing in Pakistan
When planning your project, it is essential to understand the material specifications. Glasswool is typically supplied in blanket rolls.
Standard Roll Specifications:
Thickness: 2 inches (50mm) is the industry standard for sheds in Pakistan to achieve the required thermal R-value.
Roll Dimensions: Standard rolls are typically 15 meters in length with a width of approximately 39 inches (approx. 1 meter).
Market Price: Currently, the market price for these rolls fluctuates depending on density, the type of facing (e.g., Foil-Faced or Plain), and market availability. As of early 2026, prices generally hover around the market average for standard 15-meter rolls, but always request a current quotation as steel and glasswool fiber prices are subject to global supply chain trends.
Note: For large-scale projects, we recommend opting for Foil-Faced Glasswool. The aluminum foil facing acts as a vapor barrier, which prevents moisture from entering the glasswool fibers, ensuring the insulation lasts for decades without sagging or losing its density.
The SSM Engineering Approach
At Silver Steel Mills, we don’t just supply insulation; we integrate it into the structural design. We ensure that:
Proper Installation: We secure the glasswool rolls tight against the roof underside to prevent air gaps that could reduce the insulation’s effectiveness.
System Integration: Our fabrication team pre-plans the purlin and rafter spacing to ensure the glasswool can be installed cleanly and permanently.
Longevity: We use high-quality support meshes to keep the wool from sagging over time, ensuring your shed maintains its thermal performance year after year.
Final Thoughts: An Investment in Efficiency
While the upfront cost of glasswool insulation is an additional line item in your construction budget, the Return on Investment (ROI) is undeniable. By slashing your cooling costs and improving the comfort of your livestock or employees, a well-insulated shed typically pays for itself within 2 to 3 years of operation.

Glass Wool Insulation Installation Kaise Karte Hain? (Process)
Installation Steps:
Roof Preparation: Clean roof surface. Remove any sharp objects.
Purlin Check: Ensure purlins are properly installed and spaced.
Unroll Glass Wool: Carefully unroll glass wool on the purlins. (Be careful – glass wool can irritate skin. Use gloves, mask, goggles.)
Cut to Size: Cut glass wool to fit between purlins using a long-bladed knife.
Secure in Place: Use GI wire, insulation pins, or adhesive to secure.
Overlap Joints: Overlap each sheet by a few inches to prevent heat leakage.
Apply Foil Facing: If using foil-faced glass wool, the foil should face the interior (for heat reflection).
Install Roof Sheets: Install roof sheets over the insulation (for new construction). If retrofitting: install sheets first, then insulation from inside (with hanging wires).
Important Tips:
Wear gloves, mask, goggles – glass wool fibers can irritate skin, eyes, and lungs.
Don’t compress glass wool excessively – it reduces insulation effectiveness.
Seal all joints and edges properly.

Silver Steel Mills stands out by offering premium-grade glass wool insulation at just PKR 55 per square foot, without compromising on:
Thickness (25mm to 100mm options available)
Density (12–24 kg/m³ for optimal thermal performance)

Water repellency (ideal for humid environments)
By choosing us, you’re not only saving on cost per foot—you’re investing in long-term energy efficiency, comfort, and protection.
